To all aohom it may concern Be it known that we, ANDREW Lee and residing atv Becker, in the county of Sherburne and State of Minnesota, have ini'ented'a new and useful Tractor, of which. the follow ng 18 a-specifieation.

Qnr invention relates totractors, and the main object isto provide a tractor which when drawing a cultivator will not damag the rows of corn :or other partly grown plants but is-provided "with clearings to. straddle the same. This and other objects we attain by the novelconstrueti'on and ar- I rangement of parts illustrated in the ,accomrotates one stud'lS ofa bracket 19 and has arocker arm-20connected by a, rod 21 with a similarrocker' arm'22ifixed on the-fork panying drawing,-sin which,

Figure l is atop view of our improved tractor. Fig. 2 is a rear end elevation of the tractor with some parts omitted. Fig. is a portion offthe front end of the machine in Fig. 1 with the steering niechani'sm slightly modified." Fig; dis a right hand side elevation of the tractor with the steer ing mechanism arranged asfin Fig. 3 and a" few elements partly. broken away at the middle and rear portion of the machine.

Fig. 5 is a section on the line a'a Fig. 4. Fig. 6 is a rearend elevation on a reduced scale of the machine so modified that it has clearings for one row of plants at each side of the traction wheels; in said view many parts are omitted because they are clearly I shown in other views.

Referring to the drawings by reference numeralsfl designates. the main frame of the tractor, It is supported on a front steering wheel 2 a traction wheel 3,3 which is preferably made in two wheels, and a laterally arranged supporting wheel 4, the latter is arranged'in the outer leg of a skeletoned arch 5, which arch serves to straddle the plants (see 6 fication shown in Fig. 6 thereare two arches,

5 and 5 one at each side of the inain frame. so. as to'straddle two rows of plants while I the, -traction wheels, which are arranged closely together, pass between the rows and the wheels, l, pass one 0 row. II I I In Fig. G'th wheels l, 45 are shown as fitted to slide vertically in the arches so as traction wheels 3 pass over uneven gr und, In; other respects Fig. 6 is which is broken away forward or in Fig. 2).v Inthe modi-.

tside of eachthe same as the other views, which will now be further described. I I

The fork 8 of the steering 'wheel is jour-- I ably, have a universal joint 17 as shown in Fig. i; I "In Fig. l is shown how theshaft 16 may screwis turned by a hand wheel 15 and a shaft l6 which may prefer;

extend direetlyiorward and have its screw 12'--'engaged with a W g which stem 14, whosehracket 9? is then without The action'wheelsB rotate either 0am" with their axle 23 and-to each of thern-is-secured' a-sprocket wheel 2% which is rotatedby a-link belt 25 from a' smaller sprocket.

in Fig.1 to exposean other shaft 28' below it. On the shaft 27- is fixed a gear-wheel 29, which is driven by a.

gear pinion 30 fixed on the shaft 28, and the latter shaft is rotated alternately in: opposite directions as may be required in going backward with the whole .m'a chine. I For the purpose of such rotation twoi bevel gears,

an annularly grooved sleeve 33 and slidably keyed on'the' shaft'QS. One of the wheels, 31, 32, is'in its turn rotated" by. bevel gear 34i,-which is 31, 32, are secured together by a smaller I I fiXed'oll-a shaft 35', and the latter shaft is arranged in axial alinement with the shaft 36 of an engineifl',

which is mounted on the main frame and has a combined-fly-wheel and. clutch member 38,

adapted to clutch with-a member 39 on the The latterinember being engaged having 'a rod 42 attached to a hand lever 43,

shaft 35. by a shifter lever 40 fulcru'me'cl at ti and -which by an operator (not 's'hown) on theseat- 4 4, which is mounted on a poster,

7 may be thrown into either one of two notches, l5, 4:6, in abra'cketd? fixed on' the, "rear end of the frame.

The sleeve 33 is-slid endwise by a radial arm 48 of a vertical rockshaft l9, mounted. in bearings 50, 51, (see Figs. 1 and 4) and provided with an upper rocker arm 52,

which by a rod 53 is connected with a hand lever 54, arranged to interlock alternately in two notches in a bracket 55. Upon the front end ofthe engine shaft 36'is fixed a pulley 56 by which power may be transmitted to any kind of working machinery when the tractor stands still and the engine is running, the lever 5i being placed'in the notch 54*, so as to hold both bevel gears, 31, 32, disengaged from the gear 34. The rear end of the tractor is provided with a draw bar 57, having several holes in which to attach cultiva'tors for corn and other plants planted in rows. I

From. the above description it will be understood that the engine may be started and the. tractor may be steered, reversed and stopped by the same one person, who after starting the engine occupies the seat 44. Also that the cultivator or cultivators drawn by the tractor can be arranged to Work nicely at both sides of one or two, rows of plants at a time, and that the arched form of the frame will make it pass over the L plants without injuring them; and that the skeleton form of said arches make them strong and durable without being unnecessarily heavy.

hat we claim is:

1. In a tractor the combination with an elongated narrow frame and an engine mounted thereon, of a traction wheel arranged within. the rear end of the narrow frame and operatively connected with the engine, a steering wheel supporting the front end of the frame and a draft bar at the rear end of the frame; said frame having its rear portion provided with a lateral arch and. a ground wheel mounted in the outer leg of said arch; said arch being a skeletoned framework with X-shaped braces to give it rigidity.

2. In a tractor the combination with an elongated narrow frame and an engine mounted on same, of a steering wheel supporting the frontend ofthe frame and a traction wheel supporting the rear end of the frame and oper-atively connected with the engine, said frame having its rear portion provided with two oppositely arranged lateral arches and a supporting wheel in the outer leg of each of said arches, and a draft bar at the rear end of the frame for drawing cultivators for corn or other plants arranged Lin rows, said arches being. of skeleton form and having in their upper portions diagonal crossed braces to stiffen them against forward and rearward pressure and braces to resist upward and downward pressure.

3. In a tractor the combination with an elongated narrow frame and an engine mounted thereon, of a traction wheel arranged within the rear end of the narrow frame and operatively connected with the A engine, a steering wheel supportingtthe front end of the frame and a draft bar at therear end of the frame; said frame having itsrear portion provided with a lateral arch and a ground wheel mounted inthe outer leg of said arch, said traction wheel being com-- posed of two wheels placed close together.

4:. In a tractor the combination with an elongated narrow frame and an engine mounted thereon, of traction wheels arranged within the rear end of the frame and operatively connected with the engine, a,

steeringwheel supporting the front end of the frame and a draft bar at the rear end of the frame; said frame having at each side a lateral arch with a ground wheel in the outer leg thereof, said ground wheels having a vertically yielding movement.

In testimony whereof we aflix our signatures, in presence of two witnesses,

ANDREW LEE. MILLARD LEE.
